-54 because -5(9)= -45 and -9(1)=-9 so -45-9=-54
The answer as a fraction is 1/25
The answer as a decimal is 0.04
Answer:
4
Step-by-step explanation:
-3(4x +3)+4(6x +1)=43
-12x-9 +24x +4 =43
12x - 5=43
12x=43 +5
12x=48
x=48 :12
x=4
Sientific notation is the number reduced to:
(a number more than one and less than 10) times 10^x
so in scientific notation
9.0105 times 10^11 or
9.0105e+11
Answer:
Option (3)
Step-by-step explanation:
Perpendicular lines: Perpendicular lines are the lines that intersect each other at right angles
Intersecting lines: Intersecting lines are the lines that intersect each other at a point to form angles but vertically opposite angles are equal
Hence , from above conclusion we can write Perpendicular lines must cross to form ninety degree angles, but intersecting lines cross to form angles of varying measures.
Hence , Option (3) is correct answer
